Possibly because you seem to think that all Americans have the same mentality..
(And you think the rest of the world all has the same, but different from America, mentality???)
That's a bad starting point if you're trying to understand anything...

Yes. Yes i do think America sees itself differently to the rest of the world.
As for the rest of the worlds cultures. I have friends from all over. Finland, Germany, France, England, Russia, Africa, South America, Canada, Korea, China, etc, and i can always find common ground with all of them. The only country i cannot find any is with my American friends. America is a complex and contradictory place. I believe accepting that i don't have the answers allows me to remain open minded to new ideas. Yes i am ignorant and yes i do not understand it but I embrace this ignorance because i believe admitting not understanding is the first step in aquiring wisdom. Does that make sense?
